What is the WhisperKOOL Slimline LS Cooling System?

The WhisperKOOL Slimline LS system is a specialized refrigeration unit designed for one purpose: to maintain

the optimal temperature and humidity levels conducive to the proper storage and aging of ne wines. It is a self-

contained cooling unit designed to be used as a forced-air, through-the-wall unit.

How Does the WhisperKOOL Slimline LS Work?

The WhisperKOOL Slimline LS cooling system is especially designed to maintain optimal conditions for wine storage

and aging. The system is specially designed for slow cooling, as this greatly reduces the amount of humidity removed

from the cellar.

The performance and life of your system is contingent upon the steps you take in preparing the wine cellar. Improp-

erly preparing your enclosure or incorrectly installing your unit may cause unit failure, leaking of condensation, and

other negative side eects.

It is highly recommended that you obtain the assistance of a wine storage professional.

Wine storage professionals work with licensed contractors, refrigeration technicians, and racking companies to build

well-insulated, beautiful, and protective wine cellars. WhisperKOOL has put together some useful tips to assist in the

installation process. Our recommendations are meant to act as a guide in the process of building a proper enclosure.

Your intended location may have specic needs which we do not address.

Wall & Ceiling Framing

Build wine cellar walls using standard 2x4 or 2x6 boards and ceiling joists without violating local or state codes in

your area. As a general rule, the thicker the walls and the higher the insulation value, the more consistent your cellar

temperature will be.

Insulation

Insulation is REQUIRED in order to properly use WhisperKOOL products. It is vital that all walls and ceilings be

insulated to keep the cellar temperature as consistent as possible during the summer and winter months. Standard

berglass or rigid foam insulation is normally used in cellar construction; in some cases, “blown-in” insulation is used.

The R-value, or quality of insulation, is determined by the rate at which heat passes through the insulation. The

higher the R-value, the more resistant the insulation is to conducting heat, and the more consistent your wine cellar’s

temperature will be. Using higher R-values in insulation will lower your operating costs and WhisperKOOL unit run

time. (R-13 is the recommended minimum; R-19 is preferred for interior cellar walls, and R-30 for ceilings and exterior

walls.)

Vapor Barrier

Water vapor creates its own pressure, separate from the ambient air pressure, and will intrude into colder/drier

areas. A vapor barrier is REQUIRED in order to prevent the intrusion of water vapor and maintain the correct cellar

temperature and humidity. It is recommended that 6-millimeter plastic sheeting be applied to the warm side of the

cellar walls. The vapor barrier must also be applied to the outside walls and ceiling. If it is impossible to reach the

outside, then the plastic must be applied from within the cellar. The most common method is to wrap the entire

interior, leaving the plastic loose in the stud cavity so the insulation can be placed between each stud. All of the walls

and ceiling must be wrapped in plastic for a complete vapor barrier.

In areas of high humidity, such as Southern and Gulf States, the vapor barrier will prevent inltration of warm moist

air. The moist air can cause mold to form, and standing water in drain pans promote microbial and fungal growth that

cause unpleasant odors and indoor air quality problems. If mold is found, remove it immediately and sanitize that

portion of the unit.

Note: High humidity signicantly increases the heat load on the cooling system.

Any break in the vapor barriers (cut, nail hole, over-lapping, etc.) will cause a moisture leak and must be sealed. The

electric conduit is a “duct” for vapor to travel in. The conduit should be caulked and sealed on the warm air end.

* Sizing the Unit to the Room

The specication chart will provide information on the unit’s cooling capacity. There are circumstances in which a

cellar design may require a larger unit due to preexisting design restrictions. Certain building materials such as glass,

stone, or concrete may seem adequate but do not oer the insulation capacity required to maintain the optimum

temperature for storing wine. We recommend purchasing a unit with a larger capacity to compensate for these

design limitations. Undersized cooling units can lead to premature failure and/or prevent the system from reaching

the desired set temperature. As a result, they are not covered under warranty.

PREPARING THE WINE CELLAR

Page 8 | 1-800-343-9463

SL 072820

Unobstructed Airow

Unobstructed airflow to and from the unit is critical to the unit’s overall performance and lifespan. Make sure there is a

minimum of three (3) feet of horizontal clearance in every direction around the unit (five feet is ideal). The air blown by

the fans needs to circulate and either dissipate or absorb heat from the space. The system will operate more efficiently with a

greater amount of air to exchange.

NOTE: Do not attempt to mount the unit in a wall recess or attempt to camouflage or cover the unit with any sort of aftermarket

grille, accessory, etc. This can restrict airflow, prevent the unit from working properly, and void the warranty. Please feel free to call

WhisperKOOL Customer Service with any questions or concerns regarding installation requirements.

Door and Door Seal

An exterior-grade (1¾”) door must be installed as a cellar door. It is very important that weather stripping be attached to all four

sides of the doorjamb. A bottom “sweep” or threshold is also required. The door must have a very good seal to keep the cool cel-

lar air from escaping out of the cellar. If the door does not seal properly, the unit will run continuously.

Mounting the Unit

The unit must be mounted within 18 inches of the ceiling in order to achieve sufficient cooling. As the room cools down, the

warm air will rise to the ceiling. Mounting the unit high in the room will create a consistently cool environment by capturing the

warm air and replacing it with cool air. Mounting the unit low in the room will result in a temperature variation in the room due

to (a) the unit’s inability to draw warm air down from the ceiling and (b) cold air settling to the floor.

Ambient Temperature Factor

This unit has the ability to eciently cool a wine cellar as long as the air temperature directly behind it at the coil does not

reach 85 degrees. NOTE: The ambient temperature in the venting room is not always the same as the temperature directly

behind the unit because of the heat from the exhaust fans. If you are uncertain about how the unit will function in your

location, please contact us right away at 1-800-343-9463 or suppor[email protected]

Ventilation

The necessity of dissipating heat away from the unit is critical to the unit’s performance and cannot be overstated. As the unit

operates and cools, a greater amount of heat is generated on the exhaust side of the unit. Adequate ventilation is required in

order to dissipate heat away from the unit. If ventilation is inadequate, the exhaust will heat up the area or room and adversely

aect the unit’s ability to cool.

Note: If you are unsure whether you have adequate ventilation in your installation location, please

Avoid venting to closets, bathrooms, attics, or small rooms. This can aect the

unit’s ability to eectively cool the room and void warranty.

Drain Line

All units come with a drain line for additional removal of excessive condensate. This is a backup system for the evaporator. You

are REQUIRED to install the drain line attachment. During operation, the cooling unit will strip excess water from the air in order

to maintain the proper level of humidity within the cellar. The condensate evaporator will heat and dissipate the excess moisture

through the rear of the unit. However, in extreme humidity, additional condensate will be created. High-humidity air has less

capacity to absorb additional moisture through the exhaust of the unit. The drain line will prevent overflow and leaking by

allowing for the discharge of the additional condensate. WhisperKOOL carries a condensate pump kit, which allows the excess

condensate to be pumped up to 20 feet away from the unit.

SL 072820

Electrical Needs

The Slimline system requires a dedicated 115V, 15-amp circuit. The unit draws a large amount of amps during its

initial startup. By designating a dedicated circuit breaker, you will guarantee that the unit has enough power to run

eectively. Contact an electrician for assistance with the installation of this dedicated electrical circuit:

• Match the electrical outlet to the plug provided on the WhisperKOOL unit.

• Provide a dedicated circuit and wiring for the unit.

Electrical Outlet

The accessory kit includes an 8-foot power cord which is connected to the power inlet on the side of the unit. Plug

your WhisperKOOL unit into a surge protector or power conditioner. Power surges and spikes can damage sensitive

electrical equipment. WhisperKOOL recommends plugging the unit into a surge protector or power conditioner in

order to protect your system. As outlined in our terms and conditions, power surges and spikes are not covered under

warranty.

WE RECOMMEND THAT YOU DO NOT USE A GROUND FAULT INTERRUPTER (GFI) WITH THIS PRODUCT.

NOTE: GFI’s will often nuisance trip with certain types of loads. For example, compressor motors will trip

on GFI even though there is no leakage to ground.

Test Preparation Procedure

1. Remove unit from box

2. Place unit on tabletop

3. Plug unit into an electrical outlet

4. Plug in bottle sensor

5. Turn on to test (temperature dierential should be 10°F across coils)

6. Turn o after test

7. Remove bottle probe

Testing the Unit

Place the WhisperKOOL system on a tabletop to prepare it for installation and testing. Plug the unit into a live electrical

outlet and turn it on. The unit may take up to 10 to 15 minutes before running cool. Once the operation has been

tested, turn the unit o and unplug it from the electrical outlet.

Units weigh 81 pounds and are cumbersome for one person to carry. We recommend that you get someone else to

help you during the installation process. NEVER LAY UNIT ON ITS SIDE.

If the system does not seem to be running cool after 15 minutes, please refer to the Troubleshooting Guide on page

22.

STEP 6

Slide the cooling unit back in towards the

cellar and secure it to the wall through the pre-

drilled holes on the brackets. The screws should

penetrate the studs and/or frame. Seal all cracks

and gaps around the unit with an airtight sealant

or caulking to prevent air leakage.

Note: If you use decorative moulding, it should be

attached to the walls, never to the cooling unit itself.

STEP 7

Attach the condensate drain line

The condensation drain line tube is used to remove excess condensation from the unit to a proper discharge location.

It is important that the drain line tube be properly connected to prevent leakage and other problems associated with

excess condensation.

Note: To prevent mold from growing, allow the drain line to hang above the water line.

STEP 8

If removed, reinstall the grilles on both sides of the unit and plug in the power cord. The use of an extension cord is not

recommended.

LIQUIDMEASURING THERMOSTAT SYSTEM BOTTLE PROBE

WhisperKOOL cooling units come with a liquid-temperature-measuring thermostat. The self-calibrating bottle probe

contains a sensor which communicates back and forth with the thermostat. This results in a consistent temperature

setting and accuracy. Wine should be kept at a very precise, controlled temperature and humidity.

Setting up the Bottle Probe:

1. Locate an empty wine bottle.

2. Fill it 75% full with room-temperature tap water.

3. Place bottle probe securely into bottle as seen in Figure 1.

4. Place the wine bottle in your wine cellar. Ensure sensor tip is fully submerged.

5. To ensure a consistent temperature, place bottle probe approximately three

(3) feet away from the air output and not in the flow of the air.

It is recommended that the bottle be placed in a central location of your

wine cellar. Avoid pulling too much on the probe cord. It may become

disconnected, resulting in limited functionality of the unit.

Note: The controller can be set between 50-70°F.

Remember: The WhisperKOOL unit operates based on the temperature of the water.

Do not be misled by thermostats reading air temperature. The air temperature

in the cellar will be cooler than the liquid temperature of the wine while it is

reaching the optimum balanced temperature.

Slimline LS

www.whisperkool.com | Page 15

“Def” will be displayed during the Anti-Frost Cycle. If the

cycle is less than ve minutes, the controller will prevent the

compressor from starting until ve additional minutes have

elapsed. This is to prevent short cycling of the compressor.

Holding down the UP ARROW button for approximately ve

seconds manually starts the Anti-Frost Cycle, but only if the

evaporator is below 40°F (defrost end temperature). If the

evaporator is above 40°F, the display will blink three times and

continue normal operation.

Bottle Probe Failure Protection

In the event that a bottle probe should fail, the APST (Advance

Product Safety Technology) will automatically transition the

refrigeration compressor cycles to a pre-determined time

series (40 minutes on and 10 minutes o), which will ensure

that the product is kept within a safe temperature range. P1

will be displayed on the screen until the probe issue is

rectied.

Alarms

See “Alarm Codes” in the Controller Functions chart.

PLEASE NOTE: Never insert fingers or any foreign objects

into the blower openings.

SYSTEM OPERATION

Initial Startup

When power is applied to the unit, the control will briefly

display all symbols, and the snowflake symbol will be

displayed (if unit is calling for cooling). There may be a brief

delay (up to 60 sec.) before the evaporator fan turns on. When

the evaporator fan is activated, the fan symbol will display.

Upon startup, any dust or debris on the heating element may

burn off and release an odor. The scent should dissipate in a

few hours once the dust is eliminated.

Setpoint

The setpoint is preset at the factory (WhisperKOOL) to 55°F. It

can be adjusted by the customer between 50°F and 70°F (in 1°

F increments).

Cooling Operation

Cooling is activated once the bottle probe senses a

temperature that is 1°F greater than the setpoint. The

controller then energizes the compressor relay which

activates the compressor. The evaporator and condenser fans

operate with the compressor. The unit provides cooling until

the bottle probe senses that the setpoint has been reached.

At this point the compressor relay is de-energized, which

stops the compressor. The evaporator and condenser fans will

continue to run for one minute to reintroduce any moisture

from the evaporator coil and reduce the head pressure.

Humidity Features

The Fdc parameter can be increased to allow the evaporator

and condenser fans to run for a longer period of time after the

compressor turns off, allowing more moisture to be

reintroduced into the wine cellar.

Anti-Short Cycle

The Anti-Short Cycle ensures that the compressor will remain

off for a period of three minutes after the unit has reached the

setpoint to allow the pressure in the refrigeration unit to

equalize prior to starting the compressor.

Anti-Frost Cycle (defrost)

When the evaporator probe senses a temperature of 26°F for

five minutes, the unit will enter an Anti-Frost Cycle. This will

shut down the compressor and allow the evaporator and

condenser fans to run to evaporate any frost accumulation on

the coil. The compressor will remain off until the evaporator

coil reaches 40°F, or for a maximum of ten minutes. The unit

will then return to normal operation.

If the evaporator is not above 26°F after the Anti-Frost Cycle

has ended, the red error light will display in the upper right

corner. The alarm “Ad3” will be recorded in the alarm folder,

indicating that the Anti-Frost Cycle timed out. The unit will

run for five minutes and then enter another Anti-Frost Cycle.

This sequence will continue until the evaporator temperature

rises above 26°F.

Fdc

Humidity

Management/

Enhancement

This parameter is preset to one (1) minute at the factory. This amount of time should provide adequate relative humidity for the

cellar. An increase in this parameter will keep the fan running longer after the compressor has turned o, reintroducing some

of the moisture which was extracted from the wine cellar during the cooling cycle back into the cellar. (The WhisperKOOL unit,

however, cannot increase the humidity of the cellar.) This parameter should not be adjusted below 1. Adjustments should be

made in increments of 5, with a maximum of 15 and a minimum of 1. After making any adjustment to Humidity Enhancement,

you should wait a minimum of three days before making any additional adjustments. This will allow the cellar sucient time

to acclimate to the new setting.
